In Python, sys.exit() function can also take an object other
than an integer.
If an integer is given to the argument, Python exits with the return
code of it. If a non-integer argument is given, Python outputs it
to stderr and exits with the return code of 1.
That means,
print >> sys.stderr, "Blah Blah"
sys.exit(1)
is equivalent to
sys.exit("Blah Blah")
The latter is a useful shorthand.
Note:
Some error messages in Buildman and Patman were output to stdout.
But they should go to stderr. They are also fixed by this commit.
This is a nice side effect.
